SPECIFICATION forming part of Letters Patent No. 432,555, dated July 22, 1890.

Application filed February 1, 1889. Serial No. 298,406. (No model.)

To all whom it may concern: in the water-space; but it may be otherwise Be it known that we, GRAYDON POORE and caused to part with the heat to generate steam. WVILLIAM CAMPER STOREY, subjects of the This steam may be used to propel the vessel Queen of Great Britain and Ireland, both rewhile submerged by any ordinary or suitable siding at Regent Street, in the county of Midmeans.

IO specification. A is a steam boiler of any ordinary or suit The object of this invention is to provide a able description. It is designed to supply large store of energy for use when a vesselis steam to the engine through the pipe J when submerged without having to subject the rethe boat is moving at the surface of the waceiver containing it to a high pressure, such ter. hen the boat is about to be submerged,

At posed to employ it in the propulsion of subthe same time entry of the sea to the fire-box, marine vessels by means of steam-engines. and through the fire-box to the interior of the For this purpose, according to the present inboat, is prevented by closing of the funnel- 2o vention, while the vessel is afloat in the water pvalve A. 7 fuel of any suitable kind is employed to genhen the boat is submerged, steam to work erate steam, and also to highly heat a liquid the engine is generated in the heater E by of any suitable kind having at atmospheric :the circulation therethrough of the heated pressure a boiling-point considerably higher 'liquid contained in the vessel 0.

According to one arrangement the liquid in combination of a vessel containing liquid the which heat is stored for transmission to the boiling-point of which at atmospheric press- 50 water canbe causedto circulate through tubes tire is considerably above that of water, a

heating device adapted to transmit heat to said liquid, and a fluid-pressure generator external to but capable of being placed in communication with said vessel, so that said liquid can circulate through and heat said fluid-pressure generator, substantially in the manner herein described, for the purpose set forth.

2. In a vessel constructed to travel under water, the combination of a vessel containing liquid the boiling-point of which at atmospheric pressure is considerably above that of water, a heating device, one part of which is arranged to be heated by the waste heat of a furnace, while another part is arranged to transmit heat to said liquid, wherein said heat is stored, and a fluid-pressure generator external to but capable of being placed in communication with said vessel, so that said liquid can circulate through and heat said fluid-pressure generator, substantially as described, for the purpose set forth.

3. In a vessel constructed to travel under water, the combination of a vessel containing liquid the boiling-point of which at atmospheric pressure is considerably above that of water, with a heating device and a superheater, through both of which there flows a current of steam which first receives an accession of heat in the superheater, and which then in passing through the heating device imparts a portion of its heat to the said liquid, and a lluid-pressu re generator externalto but capable of being placed in communication with said vessel, substantially as herein described, for the purpose set forth.

4. In a submarine vessel constructed to travel under water, the combination of a vesselcontainingliqnidthe boiling-pointof which at atmospheric pressure is considerably above that of water, a heating-coil arranged within but not in communication with the interior of said vessel, a steam-generator in communication with said coil, and a fluid-pressure I generator external to but capable of being placed in communication with said vessel and of being heated by said liquid, substantially as herein described, for the purpose set forth.

5. In a vessel constructed to travel under water, the combination of a fluid-pressure generator, a vessel containing liquid the boilingpoint of which at atmospheric pressure is considerably above that of water, a superheater, a heating device adapted to heat said liquid and in communication with said superheater, an auxiliary fluid-pressure generator, and a circulating-pump adapted to circulate said liquid from said vessel through said auxiliary fluid pressure generator, substantially as herein described, for the purpose set forth.

6. In a vessel constructed to travel under water, the combination of a vessel containing liquid the boiling-point of which at atmospheric pressure is considerably above that of water, with a heating device, a superheater in the flue of the main boiler, an auxiliary fluid-pressure generator for use when the vessel is submerged, and a circulating-pun] p, substantially as described, and for the purpose specified.

7. I11 a vessel constructed to travel under water, the combination of the steam-generator A with funnel-valve A, steam-pipe J, and valve K, coil B, located within the smoke-box of said generator, vessel 0, to contain liquid the boiling-point of which at atmospheric pressure is considerably above that of water, heating-coil D, located within said vessel 0 and in communication with said superheating-coil B, an auxiliary steam-generator E, pump F, and valve L, substantially as herein described, for the purposes set forth.
